Abstract: This paper reconsiders a nonlinear error-correction model of UK broad money demand by Ericsson, Hendry and Prestwich. Their model can be viewed as an approximation to a smooth transition regression (STR) type specification. The corresponding STR model, when estimated, turns out to encompass the previous model. Adopting a somewhat more general modelling approach leads to another STR model. This model variance dominates the other two but does not encompass them. Nevertheless, it fits better than the other models in the eventful 1970s and 1980s.
Keywords: Dynamic model; econometric model building; encompassing; parameter constancy; smooth transition regression.
